Increase RAM after creating container

[Marco Castignoli]

Is it possible to increase RAM of an existing container?

[sickcodes]

Yes take the image out and use :naked

[Marco Castignoli]

I saw the small section in the readme saying quite the same thing. But it's not clear what you it means to "take the image out". Thanks for your patience

[Marco Castignoli]

I just found what you mean... I suggest you to insert a link to the section "Backup the disk (Where's my disk?)" in the section "Start the same container later (persistent disk)" (if it makes sense)

[sickcodes]

Will provide instructions shortly! Did you work it out regardless?

[Marco Castignoli]

I reacreated the container before you replied 👍 very fast, so no problem man. Great work!

[Mark Chemweno]

Can you please help with the instructions about 'taking an image out'

@mchemweno : It looks like this is mentioned in the Container creation part of the docs.

Briefly, it looks something like this:

$ docker pull sickcodes/docker-osx:auto
[...]
Status: Downloaded newer image for sickcodes/docker-osx:auto
docker.io/sickcodes/docker-osx:auto

$ sudo find /var/lib/docker -size +10G | grep mac_hdd_ng.img | head -n 1
/var/lib/docker/overlay2/43736bffc5990b2c44e61c30110414b00389d18419638b1ccae1acf42df034a4/diff/home/arch/OSX-KVM/mac_hdd_ng.img

$ cp /var/lib/docker/overlay2/43736bffc5990b2c44e61c30110414b00389d18419638b1ccae1acf42df034a4/diff/home/arch/OSX-KVM/mac_hdd_ng.img ./

or in one line with something like this maybe:

$  docker pull sickcodes/docker-osx:auto && cp $(sudo find /var/lib/docker -size +10G | grep mac_hdd_ng.img | head -n 1) ./
